We all know the story. The venue has been booked and the invitations have been sent out, but those unwanted pounds just don't seem to budge.
Brides who are desperate to fit into their dream wedding dresses are willing to take extreme measures to do so, paying $1,500 (£940) to be fed through a nose drip for 10 days to lose those extra pounds in time.
The new dramatic weight-loss solution, the K-E diet, promises to help women shed up to 20Ibs in 10 days without counting calories or hitting the StairMaster.
It works via a nasogastric tube, which delivers 800 calories worth of fat, protein and water into the body every day.
Doctors claim that the solution will make the body begin to burn fat instead of sugar.
Dr Oliver di Pietro, who administers the solution in Bay Harbor Islands, Florida, told ABC News. "It is a hunger-free, effective way of dieting.
"Within a few hours, your hunger and appetite go away completely, so patients are not hungry at all for the whole 10 days. That's what is so amazing about this diet."
However, side-effects have been reported, including lack of energy, bad breath and constipation.
Despite its growing popularity in Italy, Spain and the UK, the diet has been on the receiving end of a backlash by psychologists, who warn that dropping weight so rapidly can be mentally traumatic.
Psychoanalyst Bethany Marshall, of Beverly Hills, California, told the Daily Mail: "If you lose the weight too quickly, your mind is not going to be able to catch up with a newer, skinnier you."
